以杯[4]芳烃为平台,构筑结构与识别性能独特的杯[4]芳烃衍生物是有机超分子化学的重要研究领域.本文中,杯[4]二芳胺基衍生物3与异硫氰酸苯酯反应得到开链的二硫脲基杯[4]衍生物4,产率为95%.化合物3与等物质的量对二异硫氰酸苯酯反应得到二硫脲基桥连杯[4]衍生物5,产率为80%.与过量的对二异硫氰酸苯酯反应则以产率为82%得到化合物6.化合物6进一步与水杨酰肼反应得到含硫脲基的多重氮杂杯[4]衍生物7,产率为75%.紫外光谱配合实验表明新主体分子4~7对测试的4种有机染料分子(橙黄Ⅰ、茜绿素、维多利亚蓝和亚甲基蓝)均显示出较强的配合能力,配合常数的数量级达10~5,配合比为1∶1.开链结构与多重胺基和芳基结构更有利于配位包合能力的提高.
It is an important field of organic supramolecular chemistry to construct the calix [4] arene derivatives with unique structure and recognition ability by using calix [4] arene as a platform.In this paper, Phenyl cyanate to give the open-chain dithioureido-calix [4] derivative 4 in a yield of 95%. The amount of compound 3 and the like reacted with phenyl diisothiocyanate to give the dithioureido bridge The calix [4] derivative 5 was obtained in a yield of 80% with an excess of phenyl p-diisothiocyanate in 82% yield to give compound 6. Compound 6 was further reacted with salicylic hydrazide to give thioureido-containing The yield of multiple aza-calix [4] derivative 7 was 75% .Ultraviolet spectroscopy showed that the new host molecule 4-7 pairs of the four organic dye molecules (orange yellow I, caryophyllene, victoria blue and methylene blue) Showing a strong ability to cooperate with the order of magnitude of the order of 10 to 5, with a ratio of 1: 1. Open-chain structure and multiple amino and aryl structure is more conducive to the coordination of inclusion capacity.
